You could go that route, but to be honest your best off just to stick with the OEM brand. Not to say the others are a bad product, but multi vehicle fluids especially for transmissions are just not what they’re cracked up to be. All that means is between different tested transmissions they have found a “middle ground” that works across different trannys. Some transmissions may be designed for a more viscous fluid, some less. Some may have more friction modifiers, some may require less. In a pinch if you were low or had a leak and needed a few quarts to make it home or to a mechanic it’s a great option. But long term your transmission will get most life possible using the fluid it was designed for.
I personally stick to OEM transmission fluid, for all my vehicles.
Why take a chance with an expensive transmission, since you don’t change the fluid frequently, unlike say, engine oil?
Transmissions are very complex, and I would just stick with OEM to be safe.
